Perhaps, attention has one channel, with strength {attentional capacity model}. Attentional strength correlates with general intelligence and ability to block proactive interference. Attention tries to block interference and distractions. Attention tracks goals, activates data, and calls parallel subsystems.
Perhaps, attention binds related features to produce temporarily integrated scene {coherence field} {virtual representation} [Rensink, 2000].
Perhaps, attention and visual search first process basic visual features preattentively and automatically and then use attention to associate features with objects and find higher level properties {feature integration theory}. Attention integrates or selects basic features such as color and orientation [Chun and Wolfe, 1996] [Driver and Baylis, 1998] [Duncan, 1984] [Jolicoeur et al., 1986] [Kanwisher and Driver, 1997] [Rock and Gutman, 1981] [Wolfe, 1994] [Wolfe, 1999].
Perhaps, mind transforms information flowing through one information channel, which filters information at low rate to select high-priority information {filter theory}. Filtering can affect sense input, emotion, language, color, and response. People can control information channel to block or weaken incoming messages or to interpret information differently. For example, people can keep meaningful sounds received at unattended channel from becoming conscious {Broadbent filtering effect, filter theory} [Broadbent, 1958].
Perhaps, attention and visual search process basic visual features preattentively and automatically and then use that information to control attention processes {guided search theory, attention}.
Perhaps, image features compete in decision and attention processes as mind finds, selects, and recognizes object in image {preattentive task} {pop-out task}.
Perhaps, same neurons that tell eyes to move toward location are for attention to location {pre-motor theory}. Attention changes depend on plans to move eyes to new directions [Kustov and Robinson, 1996] [Rizzolatti et al., 1994] [Sheliga et al., 1994].
Perhaps, attention uses map {saliency map} with neurons that detect differences [Itti et al., 1998] [Itti and Koch, 2000] [Itti and Koch, 2001] [Koch and Ullman, 1985] [Treisman and Gelade, 1980] [Walther et al., 2002] [Wolfe, 1994] [Wolfe, 1999].
People can make attention metarepresentations {supervisory attentional system} [Shallice, 1988].
